Did you know2024
Sona BLW Precision Forgings (Sona Comstar) is simultaneously a confirmed John Deere differential gear supplier AND a rapidly growing electric vehicle driveline component manufacturer — one of the first Indian forging companies to deliberately position itself in both the internal combustion engine ag tractor market and the EV supply chain. As John Deere moves toward electrified equipment and EV tractors (Deere's 20-year strategic roadmap includes electrification), Sona BLW's EV driveline expertise potentially positions it to supply the next generation of Deere equipment that replaces the very ICE tractors it currently serves. The forging company may follow its customer into the electric era.
Machine Maker ↗Origin2023
Sona BLW Precision Forgings (Gurugram, NSE: SONACOMS) was founded in 1995 as Sona Steering Systems, a Tier-1 automotive steering gear company. It pivoted into precision differential bevel gear forging through the 2000s, driven by the insight that differential gears require tolerances and heat treatment precision that few Indian forging companies could achieve consistently. By 2020, Sona had 5% global differential gear market share; by 2023, it had 8.1% -- achieved during a period when the company also began aggressively entering EV driveline manufacturing. The dual positioning in ICE agricultural (confirmed John Deere supplier) and EV driveline (motors, shafts, assemblies) is rare among Indian forging companies, which typically specialize in one powertrain type. BLW Precision Forgings GmbH (the BLW in the name) was a German forging company whose technology Sona acquired -- another Indian company that assembled a global-quality forging capability through acquisition of European precision manufacturing IP.
